Question

A rectangle and square are equal in area. The side of a square is 12 cm . Find the lengh of a rectangle if it is 9 m wide ?? Guys tell me what's the answer !! hurry up!!​

Answer 1

Answer:

Given:  

Side of Square =12 cm

∴  Area of square =12×12

                              =144 cm  

2

 

Now,  

let the breadth of rectangle be x

∴  Area of rectangle =Length×breadth

                              =16×x

According to question,

Both the areas are equal. So,

⟹16x=144

⟹x=  

16

144

​  

=9cm

∴breadth(x)=9 cm

Now ,  

Perimeter of rectangle =2(Length+breadth)

                                      =2(16+9)  

                                      =50cm
